Change properties of rose plot-CodePudding

I use the function rose2 in my script in order to plot a rose plot. I am working with Matlab 2016a and thus still use the rose function. I use rose2 in order to be able to set the maximum value for the r axis and fill the triangles. I use "findall" in order to rotate the location of the R-axis labels. This works very well:

maxHistogramValue = 100;

f=figure;

clf

% Set the max value to maxHistogramValue:

polar(0, maxHistogramValue,'-k')

% Set the location of the R-axis labels in degrees.
% Extract all of the 'Text' objects from the polar plot.
ax = findall(f.Children, 'Type', 'Axes');
% Filter the 'Text' objects by the 'HorizontalAlignment' property.
% PLEASE NOTE: This may not generalize to other versions of MATLAB
% where the default 'HorizontalAlignment' value for R-axis labels is not
% set to 'left'.
labels = findall(ax, 'Type', 'Text', 'HorizontalAlignment', 'left');
% Set the degrees of the R-axis Labels.
degrees = 285;
% Update the position of each R-axis label.
for label = labels'
    currentX = label.Position(1);
    currentY = label.Position(2);
    radius = sqrt(currentX^2   currentY^2);
    newX = cos(degtorad(degrees)) * radius;
    newY = sin(degtorad(degrees)) * radius;
    label.Position = [newX, newY];
end

hold on;

% Now use rose2:

rose2(inp, theta_rad)

%make transparent
alpha(0.5)

view(-90,90)

rose plot

And I figured out how to change the font size with:

labels = findall(ax, 'Type', 'Text');
for label = labels'
    label.FontSize = 16;
end

But I want to display the angles with the degree symbol. I tried to add it to the loop, but first, weired numbers are displayed and second, it also changes the r Axis, which I dont want of course.

labels = findall(ax, 'Type', 'Text');
for label = labels'
    label.FontSize = 16;
    label.String=label.String char(176);
end

Can anyone help please???

Thank you!

Try alpha(0.5), either in the rose2 function or at the bottom of your script to get the transparency you want.

Also, try polaraxes to define the font size.

ax = polaraxes;
ax.FontSize = 25;

CodePudding user response：

If you look at labels you will see that it contains more labels. You only want to modify labels(1:12):

labels = findall(ax, 'Type', 'Text');
for label = labels(1:12)'
    label.String=[label.String char(176)];
end

Also, your label.String=label.String char(176); is not matlab syntax.
